Physiotherapy & Rehabilitation Clinical Calculators

Why This Matters

Physiotherapy and rehabilitation play a critical role in restoring function and improving quality of life for millions of patients worldwide following injury, surgery, neurological events, and chronic disease. Falls are the second leading cause of unintentional injury death worldwide, affecting over 37 million people annually with significant healthcare costs. Functional assessment tools like the FIM and Barthel Index are essential for quantifying disability, setting rehabilitation goals, and measuring treatment outcomes. The Berg Balance Scale and TUG test are the most widely used fall risk assessment tools in clinical practice. The WOMAC Osteoarthritis Index is the gold standard patient-reported outcome measure for hip and knee osteoarthritis, which affects over 300 million people globally. Using standardized outcome measures is essential for evidence-based physiotherapy practice, enabling objective assessment, targeted intervention, and measurable progress tracking.

When to Use

Use the Berg Balance Scale for comprehensive balance assessment in older adults and patients with neurological conditions. Use the TUG test for rapid fall risk screening in all older patients and those with mobility concerns. Use the FIM for comprehensive functional assessment in inpatient rehabilitation settings. Use the Barthel Index for basic ADL assessment in stroke, geriatric, and rehabilitation populations. Use the WOMAC Osteoarthritis Index for monitoring symptoms and treatment response in patients with hip or knee osteoarthritis.

Available Physiotherapy & Rehabilitation Calculators

• BBS

  The Berg Balance Scale (BBS) is a 14-item objective measure designed to assess static and dynamic balance abilities in older adults and patients with neurological conditions. It is considered the gold standard for fall risk assessment in clinical practice.

• TUG

  The Timed Up and Go (TUG) test is a simple, reliable, and widely used screening tool for assessing mobility, balance, and fall risk in older adults. It measures the time a person takes to stand from a standard armchair, walk 3 meters, turn, walk back, and sit down.

• FIM

  The Functional Independence Measure (FIM) is a standardized assessment tool used to measure the severity of disability and functional status in patients undergoing medical rehabilitation. It evaluates 18 functional items across 6 domains on a 7-level scale.

• Barthel Index

  The Barthel Index is a simple, valid, and reliable instrument for measuring functional independence in activities of daily living (ADLs). It is one of the most widely used functional assessment tools in rehabilitation medicine, geriatrics, and stroke research.

• WOMAC

  The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a widely used, disease-specific patient-reported outcome measure for assessing symptoms and functional limitations in patients with hip and knee osteoarthritis.
